03G-5 Gear Washer for MX48 Power Feeder OD42mm ID38mm H6mm Installed in 03G-1 Gearbox 9.6g

Looking for the washer that sits inside the gearbox of an MX48 power feeder? The 03G-5 gear washer is that exact part: 42 mm outer diameter, 38 mm inner diameter, 6 mm high, 9.6 g each. It drops into the 03G-1 gearbox assembly and holds gear spacing and axial position, so gears stop walking on their shaft and the gearbox runs quiet again. Three diameters, one part number, no assembly around it. Price is quoted on request against quantity, and 1,000 g of stock is about 104 washers.

Three things push a power feeder gearbox onto the bench: a gear that has started to walk along its shaft, a rumble that shows up only under feed load, and a cover lifted off to reveal a polished shoulder where a flat washer should be. All three point at the same 9.6 g part.

The 03G-5 gear washer is that part. It is the internal spacer that sits inside the 03G-1 gearbox assembly of the MX48 power feeder: 42 mm outer diameter, 38 mm inner diameter, 6 mm high, 9.6 g net weight per piece. A spacer, not a bearing; nothing spins inside it.

What it does is axial. The 42 mm and 38 mm diameters leave a 2.0 mm radial wall, and that wall takes the rubbing when a gear tries to move sideways, so the shaft and the gear bore underneath stay unmarked. Gear spacing, squareness to the shaft and load spread are one job on one flat ring. Material is wear-resistant steel / alloy.

Fit is a three-number question, and the three numbers belong to one part: 42, 38 and 6 mm, read off the washer coming out rather than off the machine. At 9.6 g a kilogram of stock is about 104 washers, which is how a maintenance drawer gets sized. Price is quoted on request against quantity.

What the parts data pins down, in the order a fitter checks it:

• Three diameters, one part — 42 mm outer, 38 mm inner and 6 mm high; all three figures belong to the same 03G-5 washer.
• 2.0 mm radial wall — (42 − 38) ÷ 2, the face that carries gear load and takes the rub instead of the shaft.
• 9.6 g per piece — the fastest goods-in check at the counter, and about 104 pieces to the kilogram.
• Sized for the 03G-1 gearbox — listed as installed inside the 03G-1 gearbox assembly of the MX48 power feeder.
• Wear-resistant steel / alloy — the material listed for the part, so the ring wears instead of the gear shoulders it spaces.
• Axial location, not drive — the washer positions and spaces; torque still passes through the gear, not through the ring.
• Quiet running under load — correct spacing is what stops the gear stack shuttling and the rumble that comes with it.
• One item in the box — the line is the washer alone; no gear, no shaft and no gearbox cover is bundled with it.
• Service-drawer stock — a kilogram is 104 washers, so keeping two gearbox rebuilds on the shelf costs almost no space.

When a gearbox rumble starts, the two usual answers are a new gear or a full rebuild; a 9.6 g washer is the third.

• Fix it before the gear is scrap. The ring is the sacrificial surface, so a 42 / 38 / 6 mm washer is replaced while the gear shoulders behind it are still square.
• Change one part, keep the gearbox. 03G-5 is a washer; the gears, the shaft and the 03G-1 housing stay on the machine.
• Sized by three numbers. 42 mm, 38 mm and 6 mm can be measured on the worn washer before anything is ordered, so nobody guesses from a photo.
• Cheap to hold. At 9.6 g a kilogram is about 104 washers; a season of gearbox work fits in one small bin.
• No assembly to chase. Nothing else is needed alongside the ring: no seal, no clip, no second part number.
• Minutes, not a rebuild. The washer goes in during routine gearbox assembly or maintenance, and the cover is the only thing that comes off twice.
• Less vibration, less odd wear. Correct axial spacing keeps the gear stack from shuttling, which is where vibration and one-sided gear wear begin.
• Price matches the quantity. One washer and a box of them are quoted separately on request, so the figure follows what the workshop actually uses.

Only if the three diameters match the part coming out. 03G-5 is listed for the MX48 power feeder, installed inside the 03G-1 gearbox assembly, and measures 42 mm outer, 38 mm inner and 6 mm high. Measure the worn washer first; 42 mm on its own does not identify it.

No. 03G-5 is the washer; 03G-1 is the gearbox assembly it sits inside. One 03G-1 assembly carries a 03G-5 washer, so order 03G-5 on its own when only the ring is worn.

42 mm outer diameter, 38 mm inner diameter, 6 mm height, 9.6 g per piece. That leaves a 2.0 mm radial wall between the two diameters.

Wear-resistant steel / alloy, as listed for the part. The ring is the sacrificial face between gears, so it wears before the gear shoulders do.

About 104. At 9.6 g each, 1,000 g ÷ 9.6 g ≈ 104 pieces, which is a practical way to size a spare-parts drawer.

A spacer. It sets axial position and gear spacing; it does not carry rotation, and nothing spins inside it.

Inside the 03G-1 gearbox assembly of the MX48 power feeder. It is an internal part: the cover comes off for access and the ring locates the gear stack on the shaft.

Send part number 03G-5 with the quantity. Price is quoted on request against that quantity, so put 42 / 38 / 6 mm and the model MX48 in the same message.
